Hi there.
00:02
This question is about charles darwin in the theory of evolution.
00:10
As we're answering this, it's important to keep this historically in perspective as to when he did his work.
00:18
He published on the origin of species in 1859.
00:25
By comparison, gregor mendel, some of our first or earliest genetics experiments, published his information in 1865.
00:37
So after the theory of evolution, and that was just the beginning of some very basic genetic information.
00:45
We did not know about chromosomes and dna for many more years after that, especially the dna.
00:53
All right.
00:53
So if we look at our options here as to which of these helped darwin develop the theory by natural selection, we look at the choices.
01:05
Phenotypically offspring tend to resemble their parents more than they do random individual.
01:09
So that one is true.
01:13
Offspring resemble parents.
01:20
This was something that he noted by observation of the different species that he worked with...
